ENGLAND.

MACHINE FOR CUTTING COCOANUT-SHELLS.

SPECIFICATION forming part of Letters Patent No. 410,385, dated September 3, 1889. Application filed February 28, 1889. Serial No- 301,491. (No model.) Patented in England August 3, 1888, No. 11,254.

T0 all whom it may concern:

Be it known that I, JOHN HENRY VAVASSEUR, of Uxbridge, county of h'liddlesex, England, have invented a newand useful Improvement in Machines for Sawing or Cutting the Shells of Cocoanuts, which invention is fully set forth and illustrated in the following specification and accompanying drawings, being the same invention heretofore patented in England in English Letters Patent No. 11,254, bearing date the 3d day of August, 1888.

The object of this invention is to cut the shell of the cocoanut at its ends and sides, according to its varying thicknesses, with only a minimum waste of the kernel of the nut.

lheinvention will first be described in detail and then particularly set forth in the claim.

In the accompanying drawings, Figure 1 shows in front elevation a circulansaw ma chine embodying my invention. Fig. 2 shows Fig. 1 in plan. Fig. 3 is an end or side elevation of Fig. 1.

In said figures, the several parts are indicated by reference-letters and are described as follows:

The letter A indicates a rest or bed provided with a guard B, curved to follow concentrically a portion of the circumference of the sawI), but set alittle within the extreme points of its teeth. Said guard and rest are divided, so that the saw can revolve within a clear space, as in a slot, as clearly illustrated in the several figures. The guard is provided with a V notch or notches O. E indicates the frame provided with bearings F, in which the shaft S, carrying the saw D, is journaled. Said frame is bolted to a bed-plate G, as clearly indicated in the drawings. Power may be applied to the shaft S bya belt, a fast pulley P and a loose pulley L being provided for such purpose. The shaft S may be prolonged from the point I), where shown broken, and thereon fitted a saw similar to the saw D, with a rest A and guard B with notches C, as before described, thus making a duplex sawing-machine.

The operation of cutting the shells of the nuts is performed in the following manner: The operator, holding the nut in both hands, places it upon the table or rest A with its pointed end or nose opposite the notch or notches C in the guard B. The nut is then advanced and pressed against the guard B, so that the end or nose of the shell, whichis thicker than the sides of the shell, enters the notches C and is cut through by the revolving saw. The nut is then gradually turned or revolved on its base, nose upward, until it is completely reversed and once revolves in contact with the saw, when its shell will be completely cut-through lengthwise. This cut is of course less in depth through the thinner sides of the shell which have not entered the notches C. The nut is next placed on the rest A, on its side, and pressed against the guard B at the center of its length, when by rotating the nut the saw will cut a complete incision through its shell around its smaller circumference at. right angles to the longitudinal incision. The shell is thus divided into four segmental pieces, which may be readily pried off by any suitable inst-rumentsuch as a knife, fiat chisel, or screwdriverwithout injury to the kernel. Loss of material of the kernel is obviously saved by thus restricting the depth of the cuts to the exact or nearly exact thicknesses of the different parts of the shell.

Instead of making but one out around and lengthwise of the shell and one cut at right angles thereto, the shell may be divided by two longitudinal cuts around the shell, still cutting it into four segmental pieces.

The saws used may be made adjustable in any well-known manner, or the rest A and guard B may be made adjustable, to be advanced toward used.

llavin g thus full ydescribed my said improvement as of my invention, I claim- In a sawing or cutting machine, the combination of a saw or cutter and a rest and guard provided with a notch, as 0, whereby the depth of cut of such tool is governed and varied, substantially as set forth.
